Title: A dynamical approach on using signatures of canonical bursting model neurons to explain circuit connectivity in biological CPGs.


We investigate the effect of network connectivity on neural signatures in the central pattern generator (CPG) of the blue crab's stomatogastric ganglion. Neural signatures contain information about the interspike interval correlations of bursting neurons and are, therefore, strongly connected to the bifurcations the neuron undergoes when switching from resting to spiking state. Using the corresponding canonical models, we are able to show how circuit connectivity changes these bifurcations and, consequently, influences fundamental properties like the neuron's type of bursting or it's excitability. These results give new insight in the role of individual synaptic connections in CPGs.
